The properties of this substance are quite important. It is mostly white to white solid at room temperature. This color state characterization is conducive to observation and identification in many chemical operations and analysis.
Its melting point is also a key physical property, about 130 - 135 ° C. As an inherent property of a substance, the melting point plays a significant role in the identification of substances and the detection of purity. When it is heated, the compound will gradually change from solid to liquid within this temperature range. This process can be accurately determined by a melting point tester, providing a strong basis for quality control and purity judgment.

Suitable tetrahydroisoquinoline derivatives can be selected as starting materials.
First, 1, 2, 3, 4 - tetrahydroisoquinoline can be used as the starting material by introducing a carboxyl group at its 6 - position. A suitable electrophilic reagent can be used to introduce the carboxyl precursor into the 6-position electrophilic substitution reaction under suitable catalyst and reaction conditions, and then converted to a carboxyl group through steps such as hydrolysis. Then, under basic conditions, the nitrogen atom at the 2-position is protected by a tert-butoxycarbonyl protecting group reagent, such as di-tert-butyl dicarbonate (Boc 2O O), to obtain the target product. The reaction process requires attention to control the reaction temperature, reaction time and the ratio of each reactant to ensure the selectivity and yield of the reaction.
Second, the isoquinoline ring can also be constructed by multi-step reaction from the benzene ring with suitable substituents. For example, a specific substitution reaction is carried out on the benzene ring first, and the substituent related to the construction of the tetrahydroisoquinoline ring is introduced, and then the tetrahydroisoquinoline structure is formed through the cyclization reaction. After that, the carboxyl group is introduced at the 6-position and the tert-butoxycarbonyl protecting group is introduced at the 2-position, and the synthesis of the target product is completed with similar steps as described above. This route also requires fine regulation of the reaction conditions at each step to ensure that the reaction proceeds in the expected direction and reduce the occurrence of side reactions. During the
synthesis process, the reaction intermediates and final products need to be characterized by various analytical methods, such as nuclear magnetic resonance (NMR) and mass spectrometry (MS), to confirm the correctness of the product. At the same time, the yield of each step is calculated and optimized to improve the overall synthesis efficiency.

Bear the brunt, temperature control is extremely critical. Due to its chemical properties or temperature, it should be stored in a cool place. Generally speaking, it should be placed in an environment of 2 - 8 ° C. If the temperature is too high, it may cause its decomposition and deterioration, damage its chemical structure, reduce its purity, and then affect subsequent use; if the temperature is too low, it may also cause crystal transformation and other conditions, which is also unfavorable to its quality.
Furthermore, humidity cannot be ignored. It should be avoided from moisture, and the storage place needs to be dry. Moisture can easily cause the substance to undergo reactions such as hydrolysis and destroy its molecular structure. If placed in a place with high humidity, caking, deliquescence, etc. may occur, which seriously affects its quality and stability.
Shading and preservation are also important. This compound may be sensitive to light, and light or luminescence chemical reactions may change its chemical properties. It is advisable to store it in a brown bottle or wrap it in an opaque material to reduce the effect of light on it.
In addition, when storing, attention should also be paid to isolation from other chemicals. Because of its specific chemical properties, or reaction with certain substances, dangerous conditions such as explosion, fire, etc. Therefore, it is necessary to ensure that the storage area is clearly classified and avoid mixed storage.

Therefore, during operation, do not take it lightly, and be sure to take protective measures.
- ** Protective measures **: To ensure safety, you should be fully armed during operation. Wear protective clothing, which is the first line of defense against compounds coming into contact with the skin; wear protective gloves and choose material adapters to prevent penetration; goggles are also indispensable to avoid compounds splashing into the eyes and causing eye damage; appropriate masks should also be worn to efficiently filter harmful particles or gases that may be inhaled. < Br > - ** Storage Requirements **: Storage of this compound, environmental conditions are critical. It should be placed in a cool, dry place, away from heat and fire sources, and even cause dangerous reactions due to high temperature environment or changes in its chemical properties. At the same time, ensure that the storage place is well ventilated to prevent the accumulation of harmful gases.

Surrounding personnel should be evacuated immediately, and warning signs should be set up to prevent unrelated personnel from approaching. Emergency responders need to take good self-protection before entering the scene. When a small amount of leakage, it can be collected with inert adsorption materials, such as sand, vermiculite, etc.; when a large amount of leakage, it is necessary to build an embankment or dig a pit for containment, and then treat it with appropriate chemical methods to ensure environmental safety. If someone accidentally comes into contact, it should be dealt with quickly according to the contact method. For skin contact, rinse immediately with a large amount of flowing water; for eye contact, lift the eyelids, rinse with flowing water or normal saline, and seek medical attention in time; for inhalers, quickly leave the scene to a fresh place in the air to keep the respiratory tract unobstructed. If breathing difficulties, oxygen should be given, artificial respiration should be performed if necessary, and medical attention should be sought.
